This invention relates to machines for use in the manufacture of bootsand shoes and particularly to improved machines for pressing a sole anda shoe together to cause the sole to conform to the shape of and adhereto the shoe bottom, the illustrated machine being especially adapted foruse in the manufacture of shoes in which cement alone is relied upon toprovide permanent attachment of the sole to the shoe.

In cement attaching soles to shoes it is common pracfice at the presenttime to coat the fiesh side of an outsole and the bottom of a lastedshoewith cement, and to mount them in a selected position on aninflatable pad. After the sole and shoe have been properly positioned onthe pad they are clamped to insure against movement relatively to eachother or to the pad. The pad is then inflated to cause it to pressagainst the sole to force the sole firmly against the shoe bottom andthe pressure is maintained for a time long enough to allow the cement toset thoroughly, after which the pressure is released and the shoe withthe sole attached is removed from the pad.

In order to speed up production while yet allowing sufiicient time forthe cement to set so that the shoes can be removed from the machine, ithas been the practice in recent years to mount a plurality of pads on amachine constructed and arranged to present each pad in turn at anoperating station where a sole and a shoe may be mounted and clamped oneach pad. The pads are caused to move past the operating station,usually with a stepwise motion and to progress until they return to theoperating station. The pressure is released as, or shortly before, eachshoe reaches the operating station so that the shoe can be removed fromthe pad.

The shoes must remain under pressure until the cement has setsufficiently to hold the soles in place, which takes from fifteen tothirty minutes with much of the pyroxylin cement now in commercial use.Since only a short time is ordinarily required for mounting and clampinga sole and shoe on a pad, the rest of the pressing operation takes placewhile the pad is moving along in the machine and while other shoes arebeing positioned on other pads at the operating station. t will be seenfrom the above that, unless a large number of pads are provided in themachine so that a considerable period of time will be consumed inmounting a corresponding number of shoes on successive'pads after thefirst pad has left the operating station, the shoe on this pad will havereturned to the operating station before the cement between the sole andthe shoe bottom has had sufficient time to set properly.

Heretofore in machines which have been adapted to operate on a sole andshoe in the manner described, the inclusion of a large number of padshas frequently resulted in producing a huge, unwieldy structure whichtakes up a considerable amount of floor space. This is because the padsmust not only be spaced apart sufliciently to allow for shoe-clampingmechanism of some sort to be mounted above each of the pads, but becausethere must also be enough space left over the pads to introduce andposition a shoe and sole on each pad before the clamping mechanism isbrought into engagement with the shoe. The shoe-clamping mechanisms ordevices referred to are frequently mounted on pad boxes which carrythepads, thereby increasing the space occupied by each box so that alarge number of boxes can not be conveniently positioned in closeproximity to each other to'obtain the compact arrangement of padsdesired in a multiple-pad machine.

Important objects of this invention are to provide an improved machinefor cement attaching soles to shoes which, while having a comparativelylarge number of fluid-filled pads, will be compactly arranged and yetwill afford sufficient space at an operating station for convenientintroduction and removal of a shoe and sole,.to provide improved meansfor retaining a shoe and sole on each of a plurality of pads during asole pressing operation, and to provide mechanism in a multiple-padmachine for correctly positioning a shoe and a sole relatively to eachother on a fluid-filled pad.

With these objects in view, and in accordance with the presentinvention, the illustrated machine is provided with a plurality of padsarranged each to receive a sole and shoe, said pads being mounted in padboxes which are positioned in close proximity to each other so that thebottom of one pad box may be utilized for holding a shoe on another orthe next pad. In the illustrated machine the adjacent pads move in anendless series in a vertical plane perpendicular to a horizontal axis,each pad being presented in turn at an operating station where a soleand shoe may be positioned on its upper surface. As illustrated, eachpad is mounted in a pad box carried on the outer extremity of an armwhich is radially mounted on a stationary horizontal shaft and arrangedtorotate about the shaft to present the pads successively at theoperating station. The arrangement of the adjacent pads on radial armswhich rotate in an endless series about a horizontal axis permits acomparatively large number of pads to be utilized without causing unduebulkiness in the design of the machine. A space is provided between thearms at one point in the series, in the present case at the operatingstation, to give an operator an opportunity to introduce a sole and shoeconveniently on a pad at the operating station.

In the illustrated machine, improved means is provided for clamping ashoe and sole on each pad, said means being mounted on the bottom ofeach pad box and being constructed and arranged to engage a shoe mountedon the pad of another pad box. As illustrated herein the holding orclamping means comprises a lever pivotally mounted on ears extendingfrom the bottom surface of each pad box. Abutments carried by the leverare provided, one adapted to engage the forepart or toe portion of ashoe on a last mounted on an adjacent pad and another adapted to engagethe cone of the last. Preferably and as illustrated the toe abutment isadjustable rela tively to the lever so as to enable the abutments toaccommodate various sizes and shapes of lasts. When a sole and shoe havebeen properly positioned on a pad at the operating station, the armcarrying the pad box above this station is arranged to be lowered bytreadle controlled means into shoe-clamping position relatively to theshoe on the pad at the operating station. The shoe on the pad at theoperating station will thus be clamped by the abutments in the mannerdescribed, and the space at this station will be shifted from above thepad at the operating station to a position above the pad which is now inshoe-clamping position and which is next to be lowered into theoperating station. Thus it will be seen that while space is provided atthe operating station to permit the removal of a shoe and theintroduction of another shoe on a pad presented at this station, thereis no waste space between the pads while they are away from theoperating station.

In cement attaching soles to shoes it is important that the sole andshoe be located properly with respect to each other and that a properextension of the sole be afforded at all parts of the periphery of thesole so that a minimum of edge trimming will be required. Accordingly,means is provided in the illustrated machine for posi tioning a sole andshoe relatively to each other on a pad at the operating station, saidmeans comprising a plurality of sole engaging feelers and shoe gagesmounted on carriages located at 0-pposite sides of the operating stationand preferably being constructed and arranged to move into and out ofoperative position over each pad as the pads are presented successivelyat the operating station. In order to provide a convenient arrangementfor mounting the positioning means to operate on successive pads, and inorder that, as each pad leaves the operating station, thepositioningmeans may be withdrawn from the path of movement of the pads,the pad boxes in the illustrated machine are located with their longestaxes parallel to each other and perpendicular to the path of movement ofthe pads so that each pad will be presented side on at the operatingstation. This arrangement permits the positioning feelers and gages tobe located at opposite ends of a pad box and to be moved simultaneouslyinto and out of operative position over the toe and heel ends of eachpad from opposite ends thereof and in a direction lengthwise of thepad'box.

The positioning means as illustrated herein, is adapted to remain inclose engagement with the shoe and sole until they are secured in aselected position on a pad at the operating station, after which thefeelers and gages will be automatically withdrawn to their inoperativepositions so as not to interfere with the stepwise progression of theseries of pads.

As used herein, the word top, as applied to the pads in thisspecification and the accompanying claims, should be taken as referringto the shoe and sole supporting walls or surfaces of the pads regardlessof whether such a wall or surface is further from the center of theearth than the opposite wall or surface of a pad, either at a particularinstant or permanently, and the words bottom, over, upper, lower, etc.,as applied to the pads and pad boxes, should be taken in a correspondingsense.

The above and other features of the invention including also novel meansfor admitting fluid under pressure to the pads, novel means forautomatically restoring the pressure in and exhausting the fluid fromthe pads, and various details of construction and combinations of partswill now be more particularly described by reference to the accompanyingdrawings and thereafter pointed out in the claims.

Fig. 2 is a view in front elevation of the structure shown in Fig. 1;

Fig. 3 is a front elevation showing certain rotary valve arrangementshereinafter described; and

Fig. 4 is a sectional view, on the line 44 of Fig. 3.

The illustrated machine comprises a rectangular base 10 havingupstanding columns 12, 1 1 at opposite sides thereof. A stationary shaft16 passes transversely between the columns 12 and 14 and is secured inthe upper ends of the columns. A series of arms (in the present instancethirty) are mounted on the stationary shaft 16 and are adapted to movearound the shaft in an intermittent or stepwise manner. Each arm comprises two links 18 spaced apart along the shaft 16 and carrying attheir outer ends a hollow metal box 20. The hollow box 20 has an opentop and is arranged to hold an inflatable hollow mouldedrubber pad 22(see Figure 2), which has a flat bottom, vertical sides and a top soshaped that it will contact closely with the bottom of a shoe placedthereon. The length of the pad lies at right angles to the length of thearm, and parallel to the axis of the stationary shaft 16, as shown inFigure 2.

In order to mount the arms on the stationary shaft 16 the two links 18,forming the sides of each arm, are connected at their inner ends by ahorizontal bridge piece 24 which is adapted to be secured to ahorizontal bar 26 of a yoke member 28 (see Figure 1), the yoke memberhaving inwardly extending ears through which the stationary shaft 16passes. It is tobe understood that each arm is carried by a separateyoke and that there are, therefore, thirty similar yokes arranged on thestationary shaft. The inwardly extending ears of the yoke lie side byside along the stationary shaft and, in order that the arms carried bythe yokes may lie in a single plane at right angles to the axis of theshaft, the bridge pieces 24 which connect the inner ends of the links 18are adjustable by slot and bolt connections along the bars'26 of theyoke members. A shoe and sole may be mounted upon each pad 22 (in amanner hereinafter described) as the arm carrying the pad comes to asubstantially horizontal position in front of an operator standing inthe plane of rotation of the arms and facing the stationary shaft 16.

In order to assist the operator in positioning a sole and a shoecorrectly on the upper surface of a pad which has been presented at theoperat ing station (i. e. the position indicated at A in Figure 1),positioning means similar to those disclosed in Letters Patent of theUnited States, No. 1,897,105 granted Feb. 14, 1933 on an applicationfiled in the name of Milton H. Ballard, are provided in the illustrativemachine. Such means comprises a pair of carriages indicated at 30 and 32which carry respectively the forepart and heel end positioningmechanism, the carriage 30 and its forepart locating mechanism beingsimilar to those described in the specification above-mentioned and thecarriage 32 and the heel end positioning mechanism carried thereby beingsimilar to those disclosed in application for Letters Patent of theUnited States, Serial No. 414,516 filed Dec. 16, 1929 in the name ofSidney J. Finn. The carriages 3t, 32 are positioned on outwardlyinclined guideways 34, 36 which are secured to upwardly extendingcolumns 38, 4O projecting from the front end'of the base 10 and spacedapart suificiently to allow the pads on the arms to pass between them asthe arms move around the stationary shaft. The guideways 34, 36 extendoutwardly to the right and left of the machine an are arranged at such aheight that when a pad is in work-receiving position at the operatingstation the carriages 30, 32 may be caused to move inwardly on theirguideways toward opposite ends of the upper surface of the pad.

The carriage 30 which approaches the pad from the left carries elementshaving feelers 42 to find the toe and sides of the forepart of a solepositioned on a pad at the operating station and gage members 44 toengage the toe and sides of the forepart of a shoe to locate the latterrelatively to the former and to hold both the shoe and sole in positionon the pad. The carriage 32 which approaches the pad from the rightcarries elements similar to those disclosed in application for LettersPatent of the United States Serial No. 414,516, mentioned above, havingfeelers 46 adapted to find'the heel end of a sole and having gagemembers 48 adapted to engage the opposite sides of the heel end of ashoe. The shoe-engaging members of the elements on the carriage 32 arereleased to take up their positions by a hand lever 50 after the feelershave engaged the sole. The two carriagesSO and 32 are held outwardlyalong the guideways 34 and 36 except when they are actually in use, bymechanism hereinafter described, so as not to obstruct rotary movementof the arms about the stationary shaft 16. When the operator wishes tomake use of the positioning means to assist him in positioning a shoeand sole on a pad at the operating station, he places a sole centrallyon the pad and then trips a treadle 52 to release a pair of weights 53which, in falling, cause the carriages 30 and 32 to approach oppositeends of the pad to bring the feelers 42 and 46 into contact with theupper surface of the pad and into engagement with the sole. As thesole-engaging feelers 42 contact with the toe end and sides of the sole,they position the shoe-engaging members 44 in such a position relativelyto the sole that a shoe placed between the shoe-engaging members will becorrectly located relatively to the toe end of the sole. Similarly,after the sole-engaging feelers 46 have engaged the heel end of thesole, the shoe-positioning gage members 48, when released by depressionof the handle 50, assume correct positions relatively to the edges ofthe sole and will position the shoe relatively to the sole at the heelend. Mechanism, hereinafter described, connects the carriages 30, 32with means for rotating the arms about the axis of the stationary shaft,this mechanism also withdrawing the carriages outwardly along theirguideways 34, 36 away from the pad after pressure has been applied tothe shoe by inflation of the pad. The sole and shoe engaging elementswill, therefore, be withdrawn from over the pad to allow the pad to movedownwardly away from work-receiving position at the operating stationand to allow the pad which is immediately above to move downwardly intowork-receiving position.

The outer face of the bottom of the metal box 20 which is mounted at theouter end of each arm, has shoe engaging devices secured to it whichcomprise a member 54 adapted to press against the cone of a last in ashoe on the pad carried by the arm which lies closest to the bottom ofthe box, and a member 55 adapted to press against the forepart of theshoe.

The member 54 which is adapted to engage the cone of the last has aroughened under face and is pivoted at one end of a slotted link .53which in turn is pivoted about midway of its length on a pivot pinpassing parallel to the length of the arm between ears on the bottom ofthe box. Also pivoted on the pin 60 is another link 62 which extendsdownwardly to the left and carries at its lower end a depend ing lug onwhich is mounted, with a certain freedom of movement, the member 56which is adapted to press against a shoe just rearwardly of the toeportion. A spring 64 tends to lift the link 62 toward the bottom of thebox and an adjustable stud 66 passing through the link 62 butts againstthe under side of the left ,end of the link 58 and limits to anadjustable extent the relative heights of the two abutments 54 and 56.When a shoe and sole have been correctly positioned on a pad which is inworkreceiving position, the operator can, as hereinafter described,cause the arm above the shoe to be lowered until the shoe engagingmembers 54 and 56 carried by the arm engage the shoe and hold it againstthe pad on which it has been placed.

Means are provided in the illustrative embodiment to cause each arm,when it has been lowered toward an arm which is in work-receivingposition, to become latched to that arm in order that a shoe mounted onthe latter arm may be retained against movement during the pressureapplying operation.

To this end a transverse rod 68 (see Figure 1 particularly) passesparallel 10 the stationary raft 16, across the links 18 of each arm andon each end of the rod is rigidly secured a latch member 70. When thearm above the operating station has been brought down into shoe-jackingposition, the latch members 70 on the arm at said station engage pins'72 (see Figure 1) pro- ,iecting from the arm above and latch the armstogether. The forward portions of the tops of the latches 70 areinclined or beveled off rearwardly as rip shown in Figure 1 so that whenan arm descends toward an arm which is at the operating station, thepins 72 on the descending arm will strike the rearwardly sloping edgeson the tops of the latches and cam the latches rearwardly until slots'74 in the forward faces of the latches come into line with the pins'72, whereupon springs '78 connected to the latches will urge themforwardly to latch over the pins. Thus, an arm at the operating stationwhich has had a shoe and sole assembled on its pad will become latchedto the arm above it and the shoe, having been engaged by the shoeengaging members 54, 56 carried by the upper arm, will be held rigidlywhile the pad is inflated to press the sole against the shoe bottom.

All the arms are normally coupled to neighboring arms by their latches70, except the arm which is at the operating station and the armimmediately above it at that time. These arms are not latched to eachother while the workpositioning operation is in progress, although theyare latched to the arms on their opposite sides. Therefore, when the armwhich is immediately above the arm in work-receiving position at theoperating station is brought down into work jacking position relativelyto a shoe on the latter arm, it must be uncoupled from the arm above itand be coupled to the arm at the operating station. The mechanism bywhich each arm in turn is brought down into work-jacking positioncomprises a treadle operated lever '76 which is pivoted at '78 to acasing secured to the column 12. The pivot '78 for the lever '76 is, asseen in Figure 1, nearer the front of the machine than the stationaryshaft 16 and the lever 76 has a rearwardly projecting arm 82 extendingbeyond the shaft and provided at its rear end with a balance weight 84the purpose of which will be hereinafter explained. A trip-piece 86,comprising a lever with a pivotally mounted nose 88 at its forward end,is secured on the forward end of the lever '76. The trip-piece 86 ismounted on a horizontalpivot 90 and is connected, forwardly of itspivot, to a treadle 92 by a treadle rod 94. When an arm is at theoperating station, the forward end or nose 88 of the trip-piece 86 isarranged to lie above the end of a rearwardly projecting finger 96formed on the latch '70 at the right side of that arm which isimmediately above the arm at the operating station. When a shoe and itssole have been assembled on the pad of the arm at the operating station,the operator may depress the treadle 92 to cause the trip-piece 86 to belowered about its pivot 90 and, by engagement with the rearwardlyprojecting finger on the latch '70 on the arm which is immediately abovethe arm at the operating station, may cause both la'ches on that arm(since they are both rigidly secured to the transverse rod 68 on whichthey are mounted) to move out of engagement with the pins '72 on thenext highest arm. In order that the trip-piece 86 may be moved downward-1y to trip the latches without swinging the weighted lever '76, lostmotion (consisting of a pin on the lever which enters an arcuate slot inthe trip-piece) is provided between the trip-piece and the lever.Movement of the trip-piece in tripping the latches on the arm above theoperating station will take up this lost motion and further depressionof the treadle 92, after the latches have been tripped, will cause theweighted lever 76 to swing downwardly. The pivotally mounted nose 88 onthe trip -piece may be depressed against a spring to permit the fingers96 of the latches 7O on the arms above the trip-piece to be lowered intoposition directly under the nose of the trippiece. Each arm has a lug 98projecting from the right hand link 18 and the weighted lever '76 has asimilar lug 100 projecting laterally from its inner side. The weight onthe rear end of the lever 76 causes the forward portion of this levernormally to rise until the lug 100 thereon contacts with the lower faceof the lug 98 projecting from the arm above the work-receiving position.The arm remains in this position while the trip-piece is being moved totrip the latches to disconnect this arm from the arm above. The weight84 upon the rear end of the treadle-operated lever is somewhat greaterthan is necessary to balance both the lever and the arm which itsupports, by reason of the engagement of the lugs on the lever and armafter the latches have been tripped and, therefore, when an arm has beenunlatched from the arm above, it falls only at the speed at which theweighted lever is drawn down by the treadle 92.

As stated above, the pivot '78 for the lever '76 is nearer the front ofthe machine than the shaft 16 which forms the pivot about which the armsrotate. Consequently, the lug 100 on the lever '76 describes an arc theradius of which is considerably shorter than the radius of the aredescribed by the lugs 98 on the arms. As the arms are lowered bydownward movement of the lever '76, the above arrangement causes the lug100, which describes the smaller arc, to slide inwardly along the lug 98on each arm until it moves out of the path of the lug 98. The lever '76is then free to be carried upwardly by the weight 84 until it reachesits inoperative position as shown in Fig. 1. A dash pot is provided asshown in Fig. 1 to cushion the upward movement of the lever '76.

It will be understood, therefore, that when work is being positioned inthe machine each of the thirty arms is latched to the arm on either sideof it with the exception of the arm which is at the operating stationand the arm immediately above it. These arms, however, although notlatched to each other are latched to the arms immediately below andabove them respectively.

Means is provided in the illustrative machine to move the arms in abody, in such a manner (i. e. in a counterclockwise direction as seenfrom the right-hand side of the machine) as to carry a shoe which hasbeen jacked, downwardly from the operating. station .to bring the pad onthe arm which is next above the operating station into position toreceive a shoe. For this purpose each arm has projecting outwardly fromits right side, approximately half way along its length, a round steelpin 162. A notched steel disc 104 is provided which is adapted to berotated to engage the pins successively in order to rotate the arms. Thenotched disk 104 is mounted in a space between the arms and the column12 at the right side of the machine and is secured to the left end of ashort horizontal shaft 106 mounted in hearings in the column 12. On theother end of this shaft is mounted a worm wheel 108 (see Figure 1) and ashaft 110, passing forwardly and rearwardly of the machine through thecolumn 12 below the shaft 106, carries a worm 112 which meshes with theworm wheel 108. A swash plate clutch 114 (of the same general nature asthat disclosed in United States Letters Patent No. 1,124,620 grantedJanuary 12, 1915 on the application of Arthur E. Jerram) is mounted onthe rear end of the worm shaft 110 and a pulley 115 associated with theclutch is driven by a belt 116 from an electric motor 118 situated onthe base of the machine. A smaller notched plate 120, associated with atrip device 122 for the clutch 114, is also mounted on the shaft 106close to the plate- 104. The two notched plates 104 and 120 have thesame number of notches around their peripheries (in the present instanceseven) and a cam roll 12%: mounted. upon the upper end of a pivotallymounted bell crank lever 126 is arranged. to: run on the periphery ofthe smaller notched plate 120. A substantially horizontal arm of thebell crank lever 126 carries a stop which engages the trip device 122for the swash plate clutch 1'14 and the arrangement is such that whenthe cam roll 124 on the upper end of the bell crank lever 126 enters anotch on the small notched plate 120, as the notched plates are rotatedby the clutch 114, the trip device 122 is actuated to cause the clutchto be thrown out of driving engagement with the motor and intoengagement with a brake, thus bringing the notched plates and the armsdriven thereby to rest.

This condition app-lies as each of the arms comes successively to theoperating station.

In order to trip the swash plate clutch 114 to a cause rotation of thearms, a push lever 128 is provided which, however, operates first to putin motion driving mechanism for withdrawing the carriages 30, 32 fromthe pad which is then at the operating station. This driving mechanismcomprises a second swash plate clutch 130 similar to that previouslymentioned and also driven by a belt 132 from the electric motor 118, atrip device 134 for this clutch being coupled directly to the push lever128 by a rod 136 and a lever 136. When the clutch 130 is engaged itoperates through a worm 146 and worm wheel 142 to rotate a disc 144mounted on a short transverse shaft 146 journaled in the base of themachine. T e rotary disc 144 is provided with an eccentric pin 14.8 andhas a single notch 150 in its periphery. An upwardly extending link 152is pivotally mounted at its lower end on a transverse pin 154 secured toa parallel-linkage arrangement 156, 158 which supportsthe treadle 52controlling the feeler-carrying carriages 30, 32. The upwardly extendinglink 152 has a slot 160 in its upper end which engages the eccentric pin148 on the rotary disc 14 i.

Rearwardly of the link. 152 is a straight double arm lever 162 which ismounted on a transverse pin 16 i projecting from the machine base andwhich has an upwardly extending arm carrying a cam roll 166 againstwhich the upwardly extending link 152 is adapted to stri e as the linkis oscillated about its pivot 154 by the rotation of the rotary disc 144carrying the eccentric pin 14.8. A downwardly extending arm of the lever162 is connected by a horizontal rod 168 to a bell crank lever 170 whichis also coupled to the trip wishes to move the on which he has assernbeda shoe and sole away from the operating station and to bring an emptyarm to this station, he moves the push lever 128 rearwardly and thustrips the swash. plate clutch 130, which, through the slotted link 152and eccentric pin 148 (which at this time rests in the bottom of theslot in the slotted link), immediately depresses the treadle 52 andwithdraws the carriages 30, 32 and the members mounted. thereon awayfrom the pad. As the eccentric pin 148 moves around, it causes theupstanding link 152 to swing about its pivot 154-. and to come intocontact with the cam roll 166 on the double arm lever 162. The lever 162is rocked about its pivot 164 to trip the first-mentioned clutch 114which causes the notched. plates 104 and 120 to rotate the arms carryingthe pads. When the disc 144 has rotated through one complete revolution,the notch 15s in its periphery comes beneath a cam roll 1% on ahorizontal lever 1'36 which is connected by a rod 1'78 to the tripdevice 134 of the clutch 130-. The roll 174 is urged by a spring toenter the notch 150, thus causing the horizontal lever 176 to rocl: tothrow out the clutch. The notches in the larger notched plate 104aforementioned are spaced apart around. its periphery so that successivenotches engage pins 102 on successive arms as the latter are rotatedabout the stationary shaft 16 and, since all the arms are however, thepad on the arm next above that which was last at the operating stationwill have been brought into work-receiving position at the operatingstation. V

A safety device is provided which is arranged to prevent rearwardmovement of the push lever 126 to start the machine .until aiterthelever 76 has been loweredto bring .an arm into workljacking positionrelatively to a shoe on" an arm at the operating station. The safetydevice comprises a substantially horizontal rod 238 pivoted on cars 2&6formed on the lever '76 below its pivot '78.

The other end of the rod extends through, and is supported by, a smallopening in the push lever 128 and has a collar 242 securedto it. Thecollar ispositioned in close proximity to the in her side of the pushlever 128 to prevent rearward movement of the push lever. As theweighted lever 76 is swung about its pivot 76 and is moved downwardly tolower an arm into work jacking position, the rod 236 and the collar 242are carried rearwardly thus allowing the push lever to be movedrearwardly to trip the clutch 130. a

After a shoe and sole have been placed on the pad and, with the aid ofthe positioning fingers carried on the carriages 30 and 32, have beenpositioned thereon relatively to each other, the treadle 92, connectedto the weighted lever '76, may be depressed to cause the arm which isabove the operating station to become unlatched from the arm nextaboveit and to be lowered toward and latched to the arm which is now atthe operating station, thereby clamping the shoe and sole on the pad inproper position for a pressure applying operation. Thus it will beunderstood that each arm in turn will be rotated in a series of steps bythe driving mechanism described from the operating station (in whichposition a shoe and a sole will be assembled on the pad) downwardly pastthe operator and around the stationary shaft 16 until in turn it comesto apo- Lil,

sition above the operating station. When the arm has arrived at thisposition it will, after a shoe and sole have been positioned on the padwhich is then at the operating station, be unlatched by the operatorfrom the arm above and be brought down toward the arm at the operatingstation to become latched thereto. A further stepwise movement of thearms, due to further operation of the driving mechanism, will cause thearm referred to to descend to the operating station to permit theremoval of the shoe thereon and for the introduction of another shoe andsole.

The mechanism described so far has been concerned solely with theconstruction of the workcarrying arms, the shoeand sole-positioningmeans and the means for rotating the workcarrying arms. No means has yetbeen described for inflating the pads to cause a pressing operation totake place and, accordingly, such means will now be described. A sourceof compressed air, preferably at a pressure of about forty pounds persquare inch, supplied for example by means of a rotary compressor, isconnected by a pipe 180 (see Figure 2) to a small valve casing 182mounted below the stationary shaft 16 on the column 14. Two branch pipes184, 185 (see also Figure 3) lead from opposite sides of the valvecasing 182 and communicate (through ducts in the column 14) with radialholes in the front and rear sides of the left end of the stationaryshaft 16 where that end is supported in the column 14. The threadedholes lead into separate ducts 186, 188 (see Figure 4) formed parallelto the axis in the stationary shaft 16. A frusto-conical valve member190 (hereinafter termed the valve) is rigidly secured to the stationaryshaft 16 and is so located between the column 14 and the arms thata'threaded neck 192 (see Figure 3), extending axially from its smallerend, butts against the inner side of the column 14, the larger end ofthe valve lying nearer the arms. The valve 190 has ports formed in it.which run radially from its outer face to its inner face and theseports communicate with the two axial ducts in the stationary shaft 16.One of said ports (hereinafter termed the inlet port) shown at 194 inFigures 3 and 4, is arranged to supply fluid under pressure, such forexample as compressed air, to each pad when it has reached the operatingstation and after a shoe and sole have been assembled on and jacked tothe pad as described. The inlet port 194 communicates with the duct 186and comprises'a groove which extends axially along the outer face of thevalve for about half the width of the valve. Another port (hereinaftertermed the make-up port), shown at 196 in Figure 4 only, comprises ahollow threaded stem communicating with the duct 188 and arranged tosupply compressed air to the pads during the time that the arms movefrom the operating station-around to an exhaust position (hereinafterdescribed), to replace any air that may escape from the pads during thisperiod. The make-up port 196 leads into a rectangular cut-away portionor depression 198 sunk beneath the outer face of the valve 196. Thiscut-away portion extends around the underside of ,the valve forapproximately one fifth of the periphery of the valve, its width beingabout half the width of the valve. Two similar cut-away portions 200,202 are arranged symmetrically around the valve and communicate with thecutaway portion 198 by means of shallow grooves 204, joining themcircumferentially of the valve.

The groove of the inlet port 194 is located on the peripheral face ofthe valve in the region between the two cut-away portions 200 and 202 asshown in Figures 3 and 4. V

A frusto-conical sleeve 206 (hereinafter called the valve casing) ismounted on the valve 190 to rotate around it in company with the arms,the sleeve being mounted sufiiciently tight on the valve to provide anair-tight fit between it and the valve 190. A thrust bearing 208 (Figure3) containing a ball race is threaded on the neck 192 of the valve andbears against the smaller end of the frusto-conical valve casing 206,thus holding the latter in place on the valve. The valve casing hasthirty radial bores 210 formed in it (one for each pad), the bores beingarranged for convenience in two parallel rows as seen in Figure 3, andstaggered with respect to each other, around the peripheral face of thevalve casing. Each of the bores in the valve casing has screwed into itsouter end a nipple which connects, by a short length of metal tubing 212and a short length of flexible tubing 213, with a hollow rigid metaltube 214 (see Figure 2) which leads into one of the pads and ispositioned along the of the arm which carries that pad. The valve casing206 is connected by a metal strap 26''! to one of the arms 18 and movesaround the valve-199 asthat arm moves around the stationary shaft 16.The bores 210 in the valve casing are so arranged that they come intoalignment, one at a time as the valve casing rotates, with the inletport 194, in the valve, the valve casing being shown in Figures 3 and 4in a position in which one of the ducts is just being brought intoalignment with the inlet port. As the valve casing 206 rotates, thebores sweep over the rectangular cut-away portions 198, 200 and 262which communicate with the make-up valve 196 and each bore 210,therefore, remains in 5 communication with the air supply during thegreater part of the rotation of the valve casing before the bore comesinto exhaust position. As the valve casing"- rotates around the valve,each bore comes first into communication with the 129 inlet port, atwhich time compresed air may pass from this port through the bore into apad. The bore then comes into communication successively with the threeconnected cut-away portions from which compressed air may pass throughthe bore into the pad to supply any deficiency of air and to keep thepressure within the pad at the requisite value.

As has previously been stated, each pad-box carries on its undersideshoe-retaining members which engage a shoe on a pad on an adjacent armand, although the adjacent arms are latched together while the pressingoperation is taking place, they are unlatched before they reach theoperating station. It therefore becomes desirable, after a pad has beeninflated and has been rotated as a unit with the other arms about thestationary shaft as successive pads are presented at the operatingstation, that the pad be deflated when it reaches that position, abovethe operating station, at which. the arm which carries it is to beunlatched from the arm next above it and brought down and latched to thearm which is at the operating station. In order that the pads may bedeflated in succession as they reach the 1b position immediately abovethe operating station, the valve 190 is provided, above the inlet port194, with a third port 216 (hereinafter termed the exhaust port) withwhich the bores in the valve casing come into communication one by oneas the arms reach the position mentioned above. The exhaust portcommunicates with a third axial duct 218 in the stationary shaft 16 fromwhich the compressed air, in exhausting from each pad as the armssuccessively reach the position indicated, is allowed to escape into theat mosphere. The exhaust port 216 comprises a circular passage passingradially from the inner face of the valve toward the outer face, theouter end of the circular passage entering an L-shaped groove sunk inthe face of the valve as shown in Figure 3. The longer limb of thegroove extends along the valve substantially at right angles to the endfaces of the latter and the shorter limb extends upwardly around thevalve away from the inlet port 194 and serves a purpose later to beexplained.

The angular arrangements of the arms, the bores in the valve casing andthe inlet and exhaust ports in the valve itself are as follows.

The angle between the center lines of the exhaust port 216 and inletport 194 in the valve is 11 42 mins. (the inlet port extendinghorizontally) and the angle between successive arms when they arelatched together is also 11 42 mins. It has already been stated thateach arm in succession has to be unlatched from the arm above it andmoved down into latching position relatively to an arm at the operatingstation. This movement takes place through an angle of 8 52 mins. Thusthere exists between an arm which is at the operating station and an armwhich is above it, and which is to be brought down toward it, an angleof 11 42 mins. plus 8 52 mins., whic equals an angle of 20 34 mins. Suchan enlarged gap is provided at the operating station to allow a shoe tobe assembled conveniently on the arm which is in work-receivingposition. It will therefore be understood that the twenty-nine armswhich are not connected to the valve casing, except by the air-supplypipes which connect their pads to their bores, travel through an angleof 8 52 mins. (while the valve casing is stationary) as they movesuccessively into jacking position relatively to an arm which is at theoperating station. As before stated, the pipes 214 which connect thepads on the arms to the bores in the valve casing comprise rigid metaltubes connected to nipples in the bores by small flexible portions nearthe valve casing. Each bore which is connected to a pad on an arm whichis not secured to the valve casing is arranged 4 26 mins. (considered inthe direction of rotation of the arms) in front of the arm which carriesthe pad with which it communicates. Therefore, when the bore for one ofthe pads comes into alignment with the exhaust port 216 in the valve,that pad will exhaust although the bore is spaced 4 2 mins. in front ofthe arm carrying the pad. Now assuming the arm to be one of thetwenty-nine arms which are not rigidly securedto the valve casing itwill, after it has moved through the 8 52 mins. into jacking positionaround the valve casing, which remains at rest, take up a position 4 26in front of the bore and therefore below the exhaust port 216. When thisarm has been jacked to the one at the operating station, the arms andvalve casing will be rotated as a unit through 11 42 mins. by therotation of the notched disc 104. This rotation will present the pad onthis arm at the operating station slightly below the horizontal, (i. e.a position 4 26 mins. below the inlet port) so that the bore for thispad, which is now 4 26 mins. behind the arm and pad, will come intocommunication with the horizontal inlet port. At some time after eachpad has moved away from the operating station but before it reaches itsexhausting position, the arm which is secured to the casing will havebeen brought down from the exhausting position through 8 52 mins. intojacking position relatively to an arm at the operating station. Thevalve casing will accordingly be advanced through 8 52 mins. relativelyto the remaining twenty-nine arms and will therefore carry the bore foreach arm from its position 4 25 mins. behind the arm to its previousposition of 4 26 mins. in front of the arm, thus restoring the previousrelation between the arms and the bores for the pads on these arms.

During the 8 52 mins. movement of the arm to which the valve casing 206is secured, the bore in the valve casing for the pad on the arm at theoperating station will be carried forwardly the same distance away fromthe inlet port. In order to allow the pad on this arm to communicatewith the inlet port 194 in spite of this movement, the bore 220 for thispad is prcvidedwith a groove 222 which extends upwardly around the valvecasing forv 3 52 mins. This arrangement permits the bore for this pad toremain in com-- munication with the inlet port in spite of the movementof the valve casing. The bore 224 for the pad on the arm which issecured to the valve casing is arranged 4 26 mins. behind the armcarrying the pad and therefore compressed air will be admitted to thepad on this arm when the arm is at the operating station 4 26 mins.below the horizontal. In order that the pad on the arm which is securedto the valve casing may exhaust before the arm is moved through its 8 52mins. movement into jacking position, the shorter limb of the L-shapedexhaust port 216 runs rearwardly around the valve through an angle of 852 mins. Moreover, the limb is so placed on the valve that the bore 224for the pad on this arm can alone communicate with it,

this bore having an offset cut-away portion 226 (see Figure 3) to permitsuch communication with the shorter limb of the exhaust port.

It is to be understood that, since the sole and shoe are to be cementedtogether during the action of the machine, the sole and the lasted-overmargins of the upper are coated with cement. Preferably also, in orderthat the pressure of the pad on the shoe bottom may not disturb thebottom fillingmaterial which lies on the insole of the shoe between theoverlasted margins of the upper, the bottom filling material comprises alayer of relatively firm yet resilient felt, of a thicknessapproximately equal to that of the upper materials.

The operation of the machine is as follows:- Assuming that one of thepaclanot being the pad on the arm to which the valve casing is secured,is at the operating station, the operator placesa sole in a centralposition on the upper surface of the pad. He then trips the treadle 52to cause the carriages 30, 32 to approach the pad and the sole-engagingfeelers to come into contact with the toe and heel end of the sole. Theshoe-engaging members at the toe end assume correct positions relativelyto the toe end of the sole automatically, and the shoe-engaging membersat the heel end take correct positions relatively to the sole when theoperator depresses the hand lever 50. The operator then places a shoe onthe sole between the shoe-engaging members so that the toe and heel endsof the shoe are cor-- rectly positioned relatively to the sole and arepressing operation.

ready for the pressing operation. The operator depresses the treadle 92which is connected to the weighted lever 76 to swing the latterdownwardly and unlatch the arm next above the operating station from thearm above it and to allow the arm to descend until it becomes latched tothe arm which. is at the operating station. The shoeengaging members 54and 56 on the underside of the pad on the upper arm will then engage theshoe on the pad at the operating station. The operator then depresses atreadle 228 which, by means of a rod 230, operates a valve 232 in thevalve casing 182 (see Figure 3) to allow compressed air to be suppliedboth to the inlet port 194 and to the make-up port 196 and, through theinlet valve, to allow compressed air to enter the pad which is at theoperating station. This will have the effect of pressing the entireupper surface of the sole firmly against the lasted shoe. He nextoperates the push lever 128. The first result of the movement of thislever is to cause the clutch 130 to engage to withdraw the carriages 30,32 from the pad. As the carriages are returned to inoperative positionsthe weights 53 are raised, a latch 51 on the treadle 52 maintaining theweights in elevated position. When the latch 51 is released, thecarriages will be lowered over the next pad, so that a shoe and sole maybe positioned on that pad for a sole- After the carriages have beenwithdrawn to their inoperative positions, the clutch 130 will be thrownout of operation through the co-operation of the notched plate 144 andthe cam roll 1'74. Before this happens, however, the clutch 114, whichdrives the two notched plates 104 and 120 aforesaid, is thrown intooperation through mechanism previously described and the consequentrotation of the larger notched plate 104 causes the arms, which arelatched together, to rotate as a unit. This rotation continues until thenext highest pad (i. e. the pad on the arm immediately above that whichwas last at the operating station) is in turn presented at the operatingstation. When this has occurred the cam roll 124 which runs on theperiphery of the smaller notched plate 120 will enter one of the notchesin that plate and will cause the lever 126 which carries it to rock soas to throw the driving clutch 114 out of operation. Thus the arms willbe brought to rest with another pad at the operating station. A secondsole and shoe may then be mounted upon this pad and the operations ofcorrectly positioning the shoe and sole on the pad, of drawing down thenext highest arm and latching it to the arm carrying the shoe, ofinflating the pad, and of withdrawing the feelers from over the pad andthrowing into operation the driving clutch for the arms will berepeated. As each pad which is operating to press a sole against a shoecomes into the position above the operating station, the bore in thevalve casing 206 which communicates with that pad comes over the exhaustport 216 on the valve and the pad becomes defiated. Thus, when thetreadle 92 is depressed to lower the arm to latch it to the one beneathit, the shoe and the sole which will have been pressed to it are merelyresting by their own weight on the deflated pad and may be removedbefore the pad which is at the operating station is inflated. It iscontemplated that such time will be taken by the operator in jacking andunjacking shoes from the pads that, in conjunc tion with the timerequired for operation of the driving means, twenty minutes will haveelapsed between jacking and unjacking a single shoe and that during thistime the cement between the shoe and sole will have set.

A manually controlled valve 234 is included in each pipe 214 which leadsfrom a bore in the valve casing to a pad and each valve is so arrangedthat it normally allows direct communication between the bore and thepad. Each valve may, however, be rotated by means of a handle to cut oficommunication between the bore and the pad and to allow compressed airin the pad to exhaust through the valve into the atmosphere. Such anarrangement will be found of use if it is desired to relieve a shoe frompressure at any time after the pad on which it rests has been inflated,for example, if the shoe and sole should not, for any reason, have beencorrectly positioned.
